1.Processline
(matematica_processline_110502.ppt)
The software which makes new
software/function blocks for control
systems. Processline is the tool you need
to design your production site as good as
possible at your desk.
Output from Processline as
standardized code will save time and
errors for You.

Ex; With Processline You can:
1.Identify flow calculation errors.
2.Eliminate the errors with better code.
3.Automatic generate the code with a click on
Procesline Kodfabriken/Bigblock Tag
4.Build a ”blindtarm” (dead end) that works
side by side with the old code (if any).
5.Put the new code to work when it’s proven
stable.
Point 1-5 can reduce calculation errors from
sometimes >10 to < 0.01%.

Ex; Create a function block flow and then copy
in 3 steps 1.parameters, 2.variables and 3.code
from the report area of Processline with Ctrl-C
and paste it into the ABB function block flow
(mode structured text) with Ctrl-V
